0411 swap Issues?

C5 Scan and Tune
- forums.corvetteforum.com

I am in the process of buying a 98 c5 that has already been 0411 pcm swapped. The issue is the gas, oil gauge do not work, speedo 20mph off, traction control, abs and brake light is on. The message center flashes door ajar, traction control needs serviced, check gauges and check engine soon. I was wondering can this all be fixed in the pcm or is there somewhere else to look?

Here is the basics of my swap: 2003 LQ4 with Blue/Green PCM and TAC/pedal from the same truck. I am running a DBW 90mm LS2 silver blade throttle body WITH the X-Link conversion harness. No issues. My tuner recommends that I switch over to a 0411 PCM for more boost tuning capabilities. So my qu...

Been searching with no results for something that will at least allow me to start my swap. I've got a 6.0lq4 with an lsa top end and a 0411 pcm. Am I on my own with this or does anyone have anything? Seems there are a lot of these running around so I would think they're out there.

What is this process? Is it simple and fast? I am installing my new 4L80E and I am also upgrading to an (99+) 0411 Dual Tune PCM. Also....can my current tune in my factory 1998 PCM be pulled out (it is NOT locked) and simply downloaded into my new 0411 PCM....? Thanks. .

I have a 1998 LS1 and 4L60E running in a 1969 firebird. This is a car I am going to keep forever so I want to go ahead and swap to 99+ ECM for future upgrades and tuning simplicity. I have not licensed the current 98 computer b/c I am running a painless harness which bypasses VATS with a resistor...

Here is a wiring diagram I created for my LQ4 swap using 0411 PCM into a 1986 IROC. It uses a Current Performance Wiring fuse block. Hopefully this is useful for someone as it is very complete with wiring colors and sizes, and has some special sensor information included. The diagram does...

I have a 2000 blackbox and I am doing the swap to the 411 but unsure if I should just do the pin out route or swap the harness.I have the spreadsheet already and seems alright just a bit tedious and time consuming.... If I can easily get my hands on an 01 harness and 411 can I just do the swa...
